Description

Technical Field

[0001] This utility model relates to the field of carbon fiber reinforced plastic shell technology, specifically a honeycomb gradient impact-resistant structure for carbon fiber reinforced plastic shell. Background Technology

[0002] Carbon fiber reinforced plastic shells are high-performance composite material products made of carbon fiber and resin-based materials (such as epoxy resin, polycarbonate, etc.). Their core advantage lies in combining the high strength and stiffness of carbon fiber with the plasticity of plastic. During use, carbon fiber reinforced plastic shells incorporate a honeycomb gradient impact-resistant structure internally to increase their strength.

[0003] However, existing honeycomb gradient impact-resistant structures have poor side impact resistance and are prone to damage on the sides, affecting their strength.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a honeycomb gradient impact-resistant structure with a carbon fiber reinforced plastic shell. Summary of the Invention

[0005] The purpose of this invention is to provide a honeycomb gradient impact-resistant structure for a carbon fiber reinforced plastic shell, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a honeycomb gradient impact-resistant structure with a carbon fiber reinforced plastic shell, comprising a honeycomb panel and a reinforcing component. An outer plate is installed on the outer side of the honeycomb panel, and a carbon fiber shell is connected to the upper end of the honeycomb panel. The reinforcing component for increasing the impact resistance is disposed inside the honeycomb panel, and the reinforcing component includes a hollow cavity, a top fixing plate, a connecting rod, an inner support rod, and a bottom fixing plate. The top fixing plate is installed at the top of the interior of the hollow cavity, and a connecting rod is installed at the middle of the lower end of the top fixing plate. An inner support rod is installed on the outer side of the connecting rod, and a bottom fixing plate is installed at the lower end of the connecting rod.

[0007] Furthermore, the top fixing plate is equilateral hexagonal in shape, and the top fixing plate and the bottom fixing plate are symmetrically distributed about the horizontal central axis of the connecting rod.

[0008] Furthermore, the outer side of the outer panel is provided with assembly components for assembling the housing, and the number of assembly components is set to ten.

[0009] Furthermore, the assembly includes a connecting plate and a side bracket, with the side bracket mounted on the lower end of the connecting plate.

[0010] Furthermore, the assembly component also includes fixing holes and assembly holes. The side of the side bracket has fixing holes, and the upper and lower ends of the side bracket have assembly holes.

[0011] Furthermore, the side support frame is in the shape of a right trapezoid, and the side support frame and the fixing hole are an integrated structure.

[0012] Furthermore, the outer side of the honeycomb panel is provided with auxiliary components for edge reinforcement, and the number of auxiliary components is set to five sets.

[0013] Furthermore, the auxiliary component includes an auxiliary cavity and an auxiliary frame, and the auxiliary frame is disposed inside the auxiliary cavity.

[0014] This invention provides a honeycomb gradient impact-resistant structure for a carbon fiber reinforced plastic shell, which has the following advantages:

[0015] 1. This utility model uses the top and bottom fixed plates to provide internal support inside the hollow cavity, increasing the impact resistance of the honeycomb panel. The connecting rods provide connection and support between the top and bottom fixed plates. The three sets of internal support rods with different angles further provide internal support inside the hollow cavity, increasing impact resistance and enhancing the protective effect of the carbon fiber reinforced plastic shell.

[0016] 2. This utility model uses symmetrically distributed side fasteners to connect the honeycomb panel and the carbon fiber shell. At the same time, the side fasteners also serve to reinforce the outer side of the outer panel, increasing the overall strength of the honeycomb panel.

The top plate 402 has an impact resistance capability, and a connecting rod 403 is installed in the middle of the lower end of the top plate 402. The top plate 402 is equilateral hexagonal in shape, and the top plate 402 and the bottom plate 405 are symmetrically distributed about the horizontal central axis of the connecting rod 403. The connecting rod 403 plays a connecting and supporting role for the top plate 402 and the bottom plate 405. An inner support rod 404 is installed on the outside of the connecting rod 403. The three sets of inner support rods 404 with different angles further play an internal support role inside the hollow cavity 401, increasing the impact resistance capability and increasing the protective effect of the carbon fiber reinforced plastic shell. The bottom plate 405 is installed at the lower end of the connecting rod 403.

[0023] like Figure 3 As shown, the outer side of the outer panel 2 is provided with assembly components 5 for assembling the shell, and the number of assembly components 5 is set to ten.

The side support frame 502 and the fixing hole 503 are an integrated structure. The fixing hole 503 and the assembly hole 504 are used for quick connection of the side support frame 502, the connecting plate 501, and the outer panel 2.

The auxiliary component 6 includes an auxiliary cavity 601 and an auxiliary frame 602. The auxiliary frame 602 is provided inside the auxiliary cavity 601. The W-shaped auxiliary frame 602 in the auxiliary cavity 601 makes the honeycomb panel 1 and the outer panel 2 serve as internal reinforcement on the sides.

[0024] In summary, the honeycomb gradient impact-resistant structure of this carbon fiber reinforced plastic shell is first based on... Figures 1-3 In the structure shown, the carbon fiber shell 3 is installed on top of the honeycomb panel 1. During installation, the assembly nails pass through the fixing holes 503 and the assembly holes 504, allowing the side support frame 502 to assemble the connecting plate 501 and the outer plate 2. At the same time, the side support frame 502 plays a role in side reinforcement on the outside of the outer plate 2, increasing the overall strength of the honeycomb panel 1. The top support plate 402 and the bottom support plate 405 inside the honeycomb panel 1 play a role in internal support inside the hollow cavity 401, increasing the impact resistance of the honeycomb panel 1.
